Abstract: 1379096 Automatic speed control UNION CARBIDE CORP 31 Jan 1972 [1 Feb 1971] 4358/72 Heading G3R The speed of a D.C. motor, which may drive a consumable welding electrode, is regulated by an arrangement in which the measured back EMF of the motor is compared with a reference D. C. ramp voltage, in a differential amplifier. In the system shown, a differential amplifier 12 receives an input 1 from a sensing circuit 20 connected to motor M, and an input 2 from a reference source 14 including a ramp generator 24 synchronized with mains A. C. and a speed setting control 22 which determines the D. C. level of the ramp voltage. The output of amplifier 12 is of  constant magnitude with its polarity determined by the relative values of inputs 1, 2, so that in each half-cycle, when the level of the ramp voltage reaches the back EMF signal level, the output of the amplifier switches to negative and triggers a gating circuit 18 to supply current to the motor M for the remainder of the half-cycle. An integrating circuit 28 senses the voltage across a resistor R in the motor circuit and increases the sensitivity of the system at low speeds. A bias source 26  opposes the control source 28 to prevent anomalous operation at a zero speed setting. The gating circuit 18 includes a rectifier bridge having two thyristors connected with opposite polarity and fired by way of a Zener diode and two transistors switched by the output from amplifier 12, Fig. 3 (not shown).

Abstract: A sliding gate valve assembly employed on the side of a furnace as a furnace valve is so structured that the shut off of metal flow from the furnace occurs by directing the slide gate (21) to the up position rather than the down position. In addition, to facilitate a reduction in space at the slide gate, the slide gate is desirably configured to be asymmetrical, with the short end extending upwardly from the pour opening (29) in the nozzle. A refractory lined heat shield (26) protects the sliding gate carrier (22) and also serves to mount a collector extension (30) when used. The slide gate (21) is provided with a metallic frame (60) which retains a monolithic refractory (80) into which erosion resistant refractory inserts or performed members (29,70) are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Similarly in the stationary plate (20), means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts in the manufacture of the stationary plate. The stationary plate is symmetrical to provide full travel pressure face relationship with the sliding gate (21). Both the stationary plate (20) and slide gate (21) casting have spring pad back up reinforcements. The statutory plate desirably has means for securing a well nozzle (19) to it.

Abstract: The invention relates to a method and means for automatic analysis for determining the size distribution of particles and deviation from desired shape and colour. The method includes collection of particle samples and generation of a particle curtain in monolayer form. It is formed by taking particles through a silo whose distance (a) to a vibrating plate positioned below has a length relative to the distance (b) between the outer edge of the plate and the centre line of the silo that is large enough for the particles flowing out of the silo and down onto the plate and out over its edge to form an angle  alpha  with the horizontal plane. The angle  alpha  is 95 - 50 % of the sliding angle of the particulate material. The particle curtain is lit up and the silhouette of the particles therein is recorded and analyzed and presented in at least one place. The means includes sampler (1) plus silo (3) with at least one level sensor (4) to record the level of particles in the silo (3) and to give a signal to sampler (1). The silo (3) has a vertically displaceable extension (6) at its outlet opening. The lower part of the extension (6) is at a distance (a) from a vibrating plate (8).

Abstract: 1,190,036. Current collectors for dynamoelectric machines. GENERAL ELECTRIC CO. 28 Sept., 1967 [30 Sept., 1966], No. 44218/67. Heading H2A. [Also in Division F1] In a liquid-metal current collection arrangement, .e.g. for a disc-type homopolar machine as described in Specification 1,190,035, the migration of the liquid from one collector to the other is readjusted by moving liquid from one reservoir to another when their levels become excessively different. In the system shown, liquid migrates from collector 18 to collector 16, thus depleting reservoir 22 and over-filling reservoir 20. This imbalance is corrected when necessary by draining liquid into a sump 36 and pumping it up into the depleted reservoir 22 by means of the pressure of nitrogen 68. Circulating current is prevented by insulating pipeconnectors 48, 56, and by arranging that simultaneous exchange with both reservoirs and the sump cannot take place. The reservoirs have gas heads 30, 34 to balance the centrifugal pressure of the collectors. Selective communication of the reservoirs with the sump is allowed by electromagnetically operated valves 40, 54, the pressure head in the sump being appropriately vented to atmosphere through a regulator 74 or applied from a bottle 82. This pressure control is provided by electromagnetically operated valve 70 and ensures that alternative but not simultaneous connection to the reservoirs takes place. The liquid levels in the reservoirs are sensed by electrodes (150, 152 and 160) connected to a control circuit, Fig. 2 (not shown), energized by low-voltage A.C.

Abstract: 1475747 Platens felting G SIEMPELKAMP & CO 22 Aug 1974 [22 Sept 1973 (2)] 36901/74 Heading D1R [Also in Division B5] Fibre sheets are made by subjecting single or multilayer mats containing fibres and fluid, e.g. wet asbestos cement mats, to compression between platens by (i) applying a pressure pulse to cause felting, and then (ii) applying a consolidation pressure to effect hardening by means of the upper platen, expressed fluid being led away before and/or during compression. The pressure pulse generates a pressure higher than the consolidation pressure and produces a shock-wave which reorients the fibres. If the mat is placed on the lower platen with the interposition of a perforated screen, a needling effect may be simulated. The pressure pulse may be produced by causing the upper platen 3 to fall freely on the mat or by the release of a pressure medium from a vessel to act on said platen; as shown, the upper platen 3 and tup 7 are driven by a piston and cylinder 8 which is actuated by a feeder 16 connected to an accumulator 15 to permit free fall. A return device 9 is provided. The pressure pulse may be so adjusted as to produce a dust layer on the surface of the compressed mat and so minimise tackiness. Moisture may be led away before and during the pulse. The compression pressure is preferably built up immediately after the pulse, if necessary before the collapse thereof. The mat may be held by vacuum on a moving screen 13 which is driven over the lower platen 2. As shown in Fig. 2, this platen is provided with a coarse web 10, a fabric 11 and a fine sieve 12. The screen 13 may be replaced by a filter cloth. The platens 2, 3 may be corrugated for producing shaped sheets.
